If you like a larger diameter handlebar to hold onto, Pro's Vibe 7S Road Handlebar is just the ticket. The tops of the bar are oversize for a nice fit and feel. Plus, these trick aluminum bars are nice and stiff for excellent steering control and they're light enough to please any gram-shaver. They're also available in 3 bends so you can choose your favorite.
Which Reach and Drop you prefer depends on your hand size, arm length and riding style. If you like what you're riding, simply match it as closely as possible. In general, deeper drops and longer reaches are appropriate for riders with long arms and large hands while narrow drops and short reaches fit smaller riders. Handlebar Width is related to shoulder width. Riders usually prefer a handlebar width equal to the measurement between their shoulder blades, or slightly wider if they climb a lot or ride fast and hard.
